Abstract
ABSTRACT
Sb(III) oxidation was documented in an
Agrobacterium tumefaciens
isolate that can also oxidize As(III). Equivalent Sb(III) oxidation rates were observed in the parental wild-type organism and in two well-characterized mutants that cannot oxidize As(III) for fundamentally different reasons. Therefore, despite the literature suggesting that Sb(III) and As(III) may be biochemical analogs, Sb(III) oxidation is catalyzed by a pathway different than that used for As(III). Sb(III) and As(III) oxidation was also observed for an eukaryotic acidothermophilic alga belonging to the order
Cyanidiales
, implying that the ability to oxidize metalloids may be phylogenetically widespread.
